Does anyone who's installed the Pypes O/R H (or any after market mid-pipe) have any vibration for the first few minutes of the car running? I've got some vibration around 2K RPM but it seems to go away after the car's been running for a few minutes. I've checked all the fittings and they're tight. Anyhow, anyone got any ideas?

There is a very large shield on the 05-06 models and the extra volume created by an offroad X pipe causes a slight vibration 'sometimes'. We're still not sure why it happens on some cars and not others and why it happens on some cars for only sometimes.
